Two points to note:

1) there's no need for the parentheses in the above expression -- in fact, 
they actually change the semantics, as the "while" will be invoked in a 
subshell.

2) the exact same command (with or without the parentheses) works in ksh, 
so I was unable to reproduce the OP's problem.
